 Cr heavy metal was observed in a soil sample collected around the rice mill of Bemetara district. The analysis is done by Atomic Absorption Spectrophotometer. The soil sample is collected from 50-4500 m distance. The concentration of Cr (III) is observed 94.330 mg/kg in 50 m and 41.780 mg/kg in 4500 m. Removal of Cr (III) heavy metal is also discussed. The accumulation of various heavy metals in bioadsorbent was confirmed by FTIR. It indicates the involvement of O-H (Hydroxyl) and =CH (alkenes) groups which are metal-binding chelate. Bioadsorbent was used for the removal of toxic heavy metals from industrial effluents. SEM and EDX are also used for the characterization of bioadsorbent. It is noteworthy that even at a maximum exposure time of heavy metal and biomass, the removal of heavy metal becomes higher. The result establishes the efficiency of C. sativum as a very good adsorbent to remove the heavy metals from the soil sample as it is economical for farmers.
